Know My Number

The first step in understanding high blood pressure is learning what your numbers mean. Blood pressure is measured with two numbers: systolic (the higher number) and diastolic (the lower number) (e.g., 120/80 mmHg):

  • Systolic pressure occurs when your heart contracts.
  • Diastolic pressure occurs when your heart relaxes and fills with blood.
  • Blood pressure is measured using millimetres of mercury (mmHg), which is a standardized measurement of pressure.

The higher your systolic or diastolic blood pressure – and the longer it stays high – the greater the potential damage to your blood vessels.

Your blood pressure should be less than 140/90 mmHg.

Low Risk Moderate Risk Elevated Risk
Less than 120/80 mmHg 121/80 to 139/89 mmHg More than 140/90 mmHg

If you have diabetes, you are more likely to have high blood pressure. It should be less than 130/80 mmHg.
